MACROSOPIC DEFORMATION CHARACTERISTICS OF DONGHAI ECLOGITES IN PRE-SINIAN METAMORPHIC COMPLEX IN NORTHEASTERN JIANGSU PROVINCE
苏北东海前震旦纪变质杂岩中榴辉岩的宏观变形特征

The pre-Sinian metamorphic complex in Donghai area, Jiangsu, consists of metamorphic intrusive rocks and metamorphic layering rocks, and amongthem many eclogites widely developed and have very complicated structure. Basing on the retrogressive metamorphism-deformation sequence of eclogites that have seven structural deformation generations, we preliminarily reveal the different tectonic deformation characteristics formed in relation with P-T variation and time at different tectonic levels for each structual deformation generation of the metamorphic complex. It is helpful to study further the regularities of deformation and tectonic background of the Qinlin-Dabieshan orogenic belt.
